Xavier is expected to officially announce it is leaving the Atlantic 10 conference to join a drastically reconfigured Big East next week.

According to an ESPN report , Xavier, current A-10 member Butler and Creighton will join the seven schools that have come to be known as the "Catholic 7" in the Big East for the 2013-14 season.

Neither Xavier nor Butler had officially withdrawn from the A-10 as of Friday. The ESPN report indicates that Creighton is also waiting to formerly withdraw its membership from the Missouri Valley Conference.

Officials from the A-10 conference currently at the conference tournament in New York have not commented on the situation.

A press conference to announce the conference moves has not been scheduled as of Saturday afternoon.

According to an earlier report by ESPN's Andy Katz, Xavier and Butler will each owe the Atlantic 10 $2 million because they are required to provide a year's notice before leaving the league. A new TV deal with Fox Sports will reportedly pay each of the member schools $3 million a year.

The new Big East, which plans to retain the conference name, will have only 10 members in 2013-14. The 10 members will be the Catholic 7 schools that left the Big East -- DePaul, Georgetown, Marquette, Providence, Seton Hall, St. John's and Villanova -- plus Butler, Xavier and Creighton.

The new conference officially begins July 1, while the remaining members of the league must come up with a new conference name.

Cincinnati, South Florida and Connecticut are the only remaining members from the current Big East.

Multiple coaches from the new league had told ESPN.com that the new Big East will play an 18-game, true round-robin schedule in 2013-14. The new Big East will play its tournament at Madison Square Garden and has hired a search firm to find a new commissioner.

The league will start playing Olympic sports, such as soccer, in August.
